Macitentan, sold under the brand name Opsumit, is an endothelin receptor antagonist developed by Actelion and approved for the treatment of pulmonary arterial hypertension (PAH). Macitentan is a dual endothelin receptor antagonist, meaning that it acts as an antagonist of two endothelin (ET) receptor subtypes, ETA and ETB. However, macitentan has a 50-fold increased selectivity for the ETA subtype compared to the ETB subtype.
